Crucial 16GB Single DDR4 2400 MT/s (PC4-19200) DR x8 SODIMM 260-Pin Memory - CT16G4SFD824A

Works with my 2133mhz laptop with 4gb soldered memory

Noticable speed increase after installation.

Great memory

Bought two sticks and both seem to be dual rank (chips on both sides).

Got it early, as promised item, and performs great. Im very happy customer.

Slow but you can’t beat the price

Works just fine in the new Mac Mini once you get it installed right, which is fairly involved. Aside from the rather involved process of getting to the sockets, the sticks need to be inserted very firmly in order to work correctly. Those are consequences of the Minis design and the memory itself is as advertised and saves over 50% vs buying the memory installed by Apple.

Written by my husband: The memory is great, I bought it for a Lenovo X1 Extreme Gen2 which had a Samsung 16 GB, Sodimm ddr4, 2666ghz. At first, I thought they were not going to be compatible, but they were in the end. The crucial 32GB must be in the first slot while I swapped the Samsung to the second slot. I tried the game rise of the tomb raider, which had issues with the 16 GB RAM (the laptop has an Nvidia 1650 TI), but now runs better without being sluggish. I havent tried other functionalities like programming yet but will post another update in the upcoming months.

I purchased a refurb laptop to program amateur radios but the laptop only had 4GB of memory. I bought the Crucial memory and took my laptop to a local computer shop to install. My laptop now is the fastest computer I own. The memory works flawlessly. I trust Crucial and I know the memory will serve me well.

Did not fit my wifes HP 250-G4 laptop, but it was a 50/50 shot.
